GK300 Series
ANSI Size Electric Strike
GK300 series, ANSI-size electric strikes, accommodate up
to 15 mm latch throw in cylindrical or mortise locksets without
a deadbolt. They operate on a single voltage solenoid, 12 or
24V, and come with an optional latchbolt monitor. Stainless
steel faceplates ensure strength and long life. The lock mode
is field convertible from either fail-lock to fail-unlock.

Latch bolt
Latch-bolt lock
Nib
A latch bolt lock is a lock comprising a latch bolt and a nib.
When the door is closed, the nib makes the latch a dead bolt.
The latch bolt locks into the strike keeper in the door frame to
make sure that it is closed . Latch-bolt locks are compatible
with GK-310 and GK-311 models.
The GK-300 electric strikes can easily be changed between
fail-safe and fail-secure modes. This unique design enables
distributors to reduce inventory and still meet varying needs
and requirements of end users.
